Strong fully 3D printed 10.25" hexagonal shelf system

Hello,

This is a hexagonal shelf system made of all 3D printed parts. The shelf can be assembled in such a way that it is self-supporting when sitting on a surface, or you can arrange it however you like and hang it from the wall. Keep in mind you do not have to use every single mounting hole when hanging the shelf from the wall, but the more pieces you actually screw to the wall the stronger the shelf system will be. SolidWorks files are included for your modification. 

Let me know if you have any questions or ideas for improvements, thank you!
